The pervasive contamination of novel brominated flame retardants (NBFRs) in remote polar ecosystems has attracted great attention recent research. However, understanding regarding the trophic transfer behavior NBFRs Arctic and Antarctic marine food webs is limited. In this study, we examined occurrence trophodynamics benthic sediment collected from areas around Chinese Yellow River Station (n = 57) Great Wall 94). ∑7NBFR concentrations were range 1.27–7.47 ng/g lipid weight (lw) 0.09–1.56 lw biota, respectively, among which decabromodiphenyl ethane (DBDPE) was predominant compound all sample types. biota–sediment bioaccumulation factors (g total organic carbon/g lipid) (0.85–3.40) 4-fold higher than those Antarctica (0.13–0.61). Trophic magnification (TMFs) their 95% confidence interval (95% CI) individual ranged 0.43 CI: 0.32, 0.60) to 1.32 (0.92, 1.89) 0.34 (0.24, 0.49) 0.92 (0.56, 1.51) webs, respectively. TMFs most congeners significantly lower 1, indicating a dilution potential. This one very few investigations on ecosystems, provides basis for exploring ecological risks regions.

An emerging environmental contaminant, bis(2-ethylhexyl)-2,3,4,5-tetrabromophthalate (TBPH), can bioaccumulate in the liver and affect hepatic lipid metabolism. However, in-depth mechanism has yet to be comprehensively explored. In this study, we utilized transgenic zebrafish Tg (Apo14: GFP) image interference of TBPH on development metabolism at early stage. Using integrated lipidomic transcriptomic analyses profile remodeling effect, uncovered potential effects lipophagy-related signaling pathways larvae. Decreased contents accompanied by enhanced lipophagy were confirmed measurements Oil Red O staining transmission electron microscopy tissues. Particularly, regulatory role foxo1 factor was validated via its transcriptional inhibitor. Double immunofluorescence with biochemical analysis indicated that mitochondrial fatty acid oxidation induced reversed To summarize, our study reveals, for first time, essential foxo1-mediated TBPH-induced metabolic disorders hepatoxicity, providing new insights disease studies ecological health risk assessment TBPH.

This study investigates the process of long-term (bio)degradation polyethylene (PE) in an old municipal waste landfill (MWL) and its implications for environmental human health. Advanced techniques, such as ICP–ES/MS IC–LC, were used to analyze heavy metals anions/cations, demonstrating significant concentration deviations from control samples. The soil’s chemical composition revealed numerous hazardous organic compounds, further indicating migration additives PE soil. Toxicological assessments, including Phytotoxkit FTM, Microtox® bioassay, Ostracodtoxkit®, demonstrated phytotoxicity, acute toxicity, high mortality living organisms (over 85% Heterocypris Incongruens). An unusual contaminants MWL’s middle layers, linked Poland’s economic changes during 1980s 1990s, suggests increased risks pollutant migration, posing additional health threats. Moreover, infiltration capability microorganisms, pathogens, into structures raises concerns about potential groundwater contamination through bottom. research underscores need vigilant management updated strategies protect environment public health, particularly older sites.
